U-20 World Cup 2013 Results: Scores and Highlights from Day 13

While France advanced easily on Saturday in the U-20 World Cup, Spain was upset in one of the surprises of the tournament by Uruguay, setting up an intriguing second day of the quarterfinals.

Which Asian side would advance: Iraq or South Korea? And would Ghana continue its impressive run, or would Chile end the African nation's dreams of glory?

Let's recap an excellent day of quarterfinal play.

Iraq Defeats South Korea, 3-3 (5-4 in Penalties)

In perhaps the game of the tournament, Iraq managed to hold off South Korea and win in penalty kicks, 3-3 (5-4 in penalties). Keeper Mohammed Hameed came up huge in the penalty shootout with a timely save, while Frahan Shakor took the game-winning penalty after scoring two goals in the match.

Three times in this game Iraq would take a lead, and three times South Korea would fight back, including Jung Hyun Cheol's goal in stoppage time of the second overtime period. This was a real cracker of a contest, to say the least.

Both sides would exchange chances in the first 20 minutes, but it was Iraq that had the game's first golden chance. Kim Hyun pulled down Ammar Abdulhussein in the box in the 20th minute, giving Iraq a penalty shot.

Ali Faez stepped up and drilled the free take, and Iraq was off to an early 1-0 lead.

It would take less than five minutes for South Korea to equalize, however. Chang-Hoon Kwon rose above the Iraq defense and redirected a header into the side of the net in the 25th minute, quickly extinguishing the momentum Iraq had gained.

But the seesaw game would take another turn in the 42nd minute. Frahan Shakor buried a rebound after Ali Qasim's shot was initially saved by South Korean keeper Changgeun Lee.

Just like that, Iraq was back in front, 2-1.

The lead would be short-lived for Iraq. South Korea quickly struck in the second half, as Gwanghun Lee's header would equalize the proceedings in the 49th minute.

Both teams would have their chances down the stretch, but neither could end things in regulation. As has been a theme in the knockout stage, the game would head to extra time, a pretty brutal development for the players considering the extreme heat.

And just when it looked as though the game was destined for penalties, Iraq scored what looked to be the winner in the 118th minute.

Dhurgham Ismail took a long throw-in deep in South Korea territory and lofted the ball into the box. A brief scramble ensued, and Shakor managed to poke the ball into the net, notching his second goal of the game.

It appeared to be all over, with Iraq looking set to face Uruguay in the semifinals. Except things weren't quite done yet.

On the last play of the game, with the two minutes of stoppage time in its final seconds, South Korea shockingly equalized for a third time. Hyun Cheol's blast from range appeared to deflect ever-so-slightly off an Iraq defender and somehow made its way past keeper Hameed.

It was a remarkable goal, considering South Korea was literally seconds away from elimination and Hyun Cheol had come into the game as a 120th-minute substitution.

You couldn't have made that finish up, folks. To penalties the match would go.

After the first five takers finished the shootout tied at four makes apiece, Hameed and Shakor stepped up as heroes. Hameed guessed correctly on South Korea's sixth attempt, making a clutch save, before Shakor buried the game-winning shot.

This time, Iraq was actually off to face Uruguay in the semis, while South Korea were heading home after a valiant effort.

Ghana Defeats Chile, 4-3

If you thought Iraq versus South Korea was good, well, Ghana's 4-3 win over Chile was even better.

Seriously.

Overcoming two deficits—including one in extra time—Ghana booked its place in the semifinals behind goals from Moses Odjer, Ebenezer Assifuah (two) and Salifu Seidu.

Ghana opened the scoring in rather brilliant fashion, as Odjer netted the game's first goal in the 10th minute.

After a lovely bit of build-up play, Frank Acheampong broke into space down the left flank. He lofted a cross into the box for Odjer, who chested the pass onto his left foot and ripped home a picturesque volley just past a Chilean defender and keeper Dario Melo.

From setup to finish, it was a beautiful goal for Ghana.

But Chile would counter with its own highlight-reel worthy strike in the 23rd minute.

After Christian Bravo won the ball back, he sent Castillo down the right flank with a nice through ball. Despite having seemingly no angle to shoot from, Castillo ripped a shot over the head of keeper Eric Antwi to knot things up at a goal apiece.

Minutes later, Chile would take the lead.

Henriquez took a pass from just outside the box and turned brilliantly between two Ghana defenders before sending his shot past Antwi in the 27th minute. The finish was nice, but the turn and touch were sublime.

The game would go into the half with Chile leading 2-1, and it would hold that lead 27 minutes into the second half before Ghana evened things up when Assifuah struck.

That score was all about Clifford Aboagye, however, as he eluded several Chilean defenders with some fancy footwork before flicking a pass to Assifuah in the box. The forward knew what to do from there, putting home the equalizer.

That would be it for regulation. Fittingly, this game would become the third quarterfinal to go into extra time.

Acheampong nearly gave Ghana the lead in the first minute of extra time, but Delo just got a touch on his blistering strike and deflected it off the right post and clear of danger.

Minutes later, Castillo was sent free on a breakaway between two Ghana defenders, but Antwi made himself big in the box and smothered Castillo's low shot on goal.

Yet Henriquez would give Chile the lead in the 98th minute, scoring his second goal of the match.

Claudio Baeza played a lovely ball into the box over Ghana's defense and Henriquez timed his run perfectly, remaining onside and heading home Chile's third goal. It was a fantastic read and pass from Baeza, though Ghana will certainly lament the defensive lapse.

Ghana wasn't finished just yet, however, tying the game in the 113th minute.

After another bit of lovely build-up play, Clifford Aboagye came away with the ball atop the box after a shaky touch. He found Seidu open down the right and midfielder came up huge, smashing home an equalizer.

But if you thought that goal was something to see, well, Ghana's game-winner in the 121st minute was one for the ages.

Acheampong made a run down the right side that defies most superlatives, somehow controlling the ball just as he reached the touchline and lofting the ball back toward the box. There, Assifuah met it with a weak header that should have been cleared off the line but somehow found its way through two Chilean defenders and Delo to give Ghana the win.

Honestly, you'd be hard-pressed to find two crazier games, back-to-back, than Sunday's quarterfinals at the U-20 World Cup. Chile will now face France in the semifinals.
